WebDNA is a long polymer made from repeating units called nucleotides. The structure of DNA is dynamic along its length, being capable of coiling into tight loops and other shapes. In all species it is composed of two helical chains, bound to each other by hydrogen bonds.Both chains are coiled around the same axis, and have the same pitch of 34 ångströms (3.4 nm). Web1.Introduction. The structure of 1-ethyl-3-methyl-imidazolium dicyanamide ([EMIM][DCA]) ionic liquid (IL) is reported to be stabilised by the presence of hydrogen bond between …
